[Elecraft] P3 MKR off freq?

[Gary Ferdinand]

I'm sure this is "user error," but so far this user fails to figure it out.
This started happening right around the time I loaded the current firmware
into both the K3 and the P3.  When I tune or recall a memory in the K3, the
P3 correctly displays the frequency and it appears to be centered within the
brackets on the smallest scan.  However, when I use either marker and line
it up with a signal off the current K3 frequency and tap select on the P3,
the end result on the K3 is off about a KHz and this also shows up on the P3
- ie the signal I thought I put the marker on is now showing up down from
current frequency.

Any ideas?  Yes, I have calibrated the P3 according to the instructions on
p19 of the manual, and the transceiver settings are unchanged and specify
K3.

Thanks in advance.... Gary W2CS
